SHUT-OUT DEVICE AND THE LIKE.

Application filed January 10, 1921. Serial No. 436,219.

To all whom it may concern:

Be it known that 1, JOHN H. SHAW, a citizen of the United States,residing in New Haven, county of New Haven, State of Connecticut, haveinvented certain new and use ful Improvements in Shut-Out Devices andthe like, of which the following is a full, clear, and exactdescription.

This invention relates to shut-out devices, and more particularly to adevice which is adapted to be locked in the keyhole of a door to preventthe insertion of the usual key therein. Such a device is sometimesnecessary to prevent the door being unlocked by an unauthorized person.

hen salesmen visit hotels, it is common for them to arrange a display oftheir goods in the rooms of the hotel and bring their customers in toexamine them. In such cases it is desirable for the salesman to beprovided with a key or some means of looking his door from the outsideso that no one, not even the employees of the hotel, may enter while heis absent. It will, moreover, be

found desirable in many other casesfor guests of hotels to have keys orshut-out de vices which will enable them to secure their doors from theoutside against the entry of an unauthorized person. For this purpose itis sometimes the custom to give such guests or salesmen a display-key,which will, when used, lock the door of the room from the outside, sothat it may only be opened by use of a master key or a key in the handsof a manager of the hotel, or someone in authority. The employees areenabled though at times to have duplicates of these keys made, whichwill, of course, enable them to secure entrance to the rooms even whenthey have not been given these master keys. Such an arrangement,moreover, requires one of these display keys for each door, asof course,they must all be different, and when one is lost, the lock must be takenoff and a new key made, or it is useless for this purpose.

I have found it to be very desirable to provide a simple unitary devicewhich will enable a person to lock his door from the outside and be surethat no one will be able to gain entrance during his absence. Moreoverthe device which I have invented will be universal in its use, as it maybe apshut-out device.

plied to all locks which have keyho-les for the insertion of wing keys.

One object of my'inventio-n is to provide a shut-out device which may besecurely locked within the keyhole of the door and prevent the insertionof the key therein.

Another object of my invention isto provide a unitary device of theclass described, which will be applicable to any door and still beeffective to prevent the unlocking of the door. c e

A still further object of my invention is vto provide a' device of thecharacter described, which will be universal in its use in that it maybe applied to any door.

A still further object of my invention is to provide a shut-out device,which will close the keyhole of a door against the insertion of a keytherein, and one which may Fig. 2 is a fragmentary sectional View of p lthe door and lock case, a part of the case being broken away for thesake of clearness;

Fig. 3 is a sectional view along the line 33 of Fig. 2; v

Fig. 4 is a top plan view of the parts shown in Fig. 3;

Fig. 6 is a front elevational view of my shut-out device removed fromthe door; and Fig. 7 is a side elevational view of the same with the keyinserted'therein;

To accomplish the results and objects heretofore set forth, I haVeprovided a plug which is insertable into the keyhole of a door and isadapted to be lo ckedagainst removal therefrom except by the use of theproper key. Fig. l of the drawings shows a section of a door at 10,pro-vided with an escutcheon plate 11 and a door lock provided with aface plate 12 and a lock case 13. A keyhole 14 upon the outside of thedoor is adapted to admit a key for the operation of the dead bolt 15after the usual manner.

My shut-out device consists of a plug 16, which is adapted to beinserted into the keyhole 1a of the door. This plug 16 is adapted to beinserted far enough into this keyhole to abut against the lock case 13adjacent the keyhole 17 formed in the same for the admission of theregular key. The plug 16 is provided with a lock case 18, which isformed integral with the plug in the embodiment shown, although thearrangement of this detail may be varied, if desired, which contains pintumblers 19 adapted to cooperate with the pin tumblers 21 provided in akey barrel 20 rotatably mounted in.th lock case 18. The portion of theplug which forms this lock case is made larger, as shown in Fig. 4-,than the remainder of the plug, so that the lock case will not beadmitted to the keyhole 14:. The size of this lock case, however, is notessential to all aspects of the invention, but may be varied so thateven the lock case itself may be small enough to he admitted into thekeyhole 1a.

A key 22 of the form commonly used with pin tumbler locks is provided tooperate the key barrel 20 within the lock case 18. The key barrel is, asstated, rotatably mounted within the lock case 18 and the pins 21 withinthe barrel cooperate with the pin tumblers 19 in the lock case in theusual way. The key can, in the arrangement shown, be removed from thelock case only when the salts are in locked position, as shown in igs.2, 4L, 5 and 6, so that when the shutout device is inserted into thekeyhole of a door, the occupant of the room may be sure that when he isenabled to remove the key, the plug is securely locked in position toclose the keyhole.

The key barrel 20 is provided with an extension 23. secured thereto forrotation therewith. This extension 23 is provided with a reduced end 24formed with a shoulder 24L and carrying a wing 25, which reduced end andwing are adapted to project within the lock case, and when the wing hasbeen turned out of alignment with the keyhole 17 of the lock case, theplug will be prevented from removal from the keyhole of the door. Theextension 23 is secured to the key barrel 20 by being provided with atongue 26, which fits within a recess 27 formed in the key barrel and issecured therein by a pin or rivet 28. The particular connection betweenthese two parts, however, is not essential to the invention and the twoparts may be formed. in one piece, if desired. The extension 23 is thusrotatably mounted above the plug 16 and will be turned by the rotation01" the key barrel. A. pin29 mounted in the lock case projects into agroove 30 formed in the key barrel to limit the rotation of the latterto a fraction of a turn. As shown, the key barrel enjoys only aboutone-eighth of a turn, but this, of course, may be varied, as desired.

The operation of my device is as follows: When a guest desires to lockhis door from the outside against intrusion, he is given my shut-outdevice and key, as shown in Fig. 7. The door to his room would first besecurely locked from the outside by the usual key and then my improvedshut-out device would be inserted into the keyhole until the shoulder24: abuts against the lock casing, the wing 25 being received within thelock case upon the door. The wing would then be in the dotted lineposition shown in Fig. 5. A slight turn of the key to the position shownin Fig. 4 would turn the wing to the position shown in Fig. 5 and thewing would then be prevented from passing out through the keyhole, sothat the shut-out device could not be removed from the door. The lockcasing will then be engaged between the wing and the shoulder 25% on thestem. The guest of the room would then be assured as long as he retainedpossession of the key 22 that no master key or device of any kind couldbe inserted in the keyhole 1 1 to operate the lock bolt 15 to gainaccess to the room.

It will be seenthat a hotel or roominghouse may be provided only with alimited number of these shut-out devices, as they are adapted to beusedwith any door, and are not restricted to the lock for which they areespecially made, as is-the case with a display key.

My device might also be Very useful to prevent door locks being forcedor picked by the insertion of a tool intothe keyhole for this purpose.It is usually the case that a lock with whicha wing key is employed iseasier to pick or force than a pin tumbler look, so that my shut-outdevice might be applied to such a lock to make it safer. Such anapplication would, in effect, transform such a lock from a wing key lookinto a pin tumbler lock.

lVhile I have shown and described a pre ferred embodiment of myinvention, it is to be understood that the same is not to be limitedthereto in all of its details, but that various changes andmodifications may be made which will lie within the spirit of theinvention and within the scope of the appended claims.
